Description

Technical Field

[0001] This invention relates to the field of H-beam technology, and more specifically, to an anti-deformation device and method for H-beams. Background Technology

[0002] H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section resembling the letter "H". They are suitable for building floor beam and column structures and have the advantages of strong bending resistance, simple construction, and cost savings. However, the joints of H-beams have a large load-bearing capacity, and there is a possibility of tension and compression at the flanges of the joints, which may cause the H-beams to deform over time.

[0003] Chinese Patent CN116460508 A, "Anti-deformation Device for H-shaped Components," discloses an anti-deformation device for H-shaped components, used to suppress welding deformation of H-shaped components. The device includes a fixed frame, a first pressing assembly, and a second pressing assembly. The fixed frame includes a first connector and a second connector arranged opposite to each other along the height direction of the H-shaped component. The first connector abuts against a first flange, and the second connector abuts against a second flange, jointly clamping and positioning the H-shaped component. One end of the first pressing assembly is connected to the fixed frame, and the other end is used to press against the web plate along the width direction of the H-shaped component. This invention uses a movable bracket, a support bracket, and a wedge-shaped bracket to reinforce and support the flanges at the H-shaped steel joints, effectively preventing deformation at the flanges and increasing the load-bearing capacity of the H-shaped steel. The pushing mechanism allows for convenient adjustment of the total length of the movable bracket and the support bracket, facilitating connection of the movable bracket and the support bracket to the flanges at the H-shaped steel joints, making operation convenient. Summary of the Invention

[0004] 1. The technical problem that the invention aims to solve

[0005] To address the shortcomings and deficiencies of existing technologies, this invention provides an anti-deformation device and method for H-beams. The purpose of this invention is to provide an anti-deformation device for H-beams that solves the problem of weak strength and easy deformation at the flanges of H-beam connection nodes. By using a movable bracket, a support bracket, and a wedge-shaped bracket, the flanges at the H-beam node can be reinforced and supported, effectively preventing deformation at the H-beam flanges and increasing the load-bearing capacity of the H-beam. The pushing mechanism allows for convenient adjustment of the total length of the movable bracket and support bracket, facilitating connection of the movable bracket and support bracket to the flanges at the H-beam node, making operation convenient.

[0006] 2. Technical Solution

[0007] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0008] The present invention provides an anti-deformation device for H-beams, comprising an H-beam, a movable bracket, a support bracket, and a wedge-shaped bracket. The movable bracket and the support bracket are slidably connected, and their total length can be adjusted when they slide. The wedge-shaped bracket is abutted between the movable bracket and the support bracket.

[0009] The wedge-shaped bracket has a groove at its bottom, and correspondingly, the support bracket surface is provided with an inclined block.

[0010] The movable support is provided with a pushing mechanism on the outside. The side of the inclined groove and the inclined block closest to the pushing mechanism is the lower end. The pushing mechanism is used to push the wedge-shaped support to move laterally. Under the squeezing cooperation of the inclined groove and the inclined block, when the wedge-shaped support is pushed inward, the total length of the movable support and the support support is extended to support the H-beam. When the wedge-shaped support is pushed outward, the total length of the movable support and the support support is shortened, so that the support structure can be disassembled from the H-beam.

[0011] Furthermore, the wedge-shaped bracket is located in the middle of the movable bracket and the supporting bracket, and the upper and lower ends of the wedge-shaped bracket abut against the movable bracket and the supporting bracket respectively, and the wedge-shaped bracket can move laterally.

[0012] Multiple inclined blocks are spaced apart on both sides of the support block, and the number of inclined blocks corresponds to the number of inclined grooves to increase the support capacity;

[0013] The angle of the inclined block is 5°. When designing the tilt angle of the inclined block, ensure that the friction angle is greater than or equal to the transmission angle. Utilize the self-locking property of the inclined surface to ensure that the inclined block will not move outward on its own when subjected to a force perpendicular to the flange of the H-beam.

[0014] Furthermore, the movable support includes a track, and a vertical groove is formed in the track;

[0015] The support bracket includes a support block and a slide rail fixed to one side of the support block. The support block slides into the slide rail through a vertical groove on the inner side of the track. The support block is slidably inserted into the track. The vertical groove is adapted to the cross-section of the slide rail to increase the stability of the support bracket and the movable bracket.

[0016] Furthermore, the movable support also includes a first clamp fixed to the upper side of the track, and a first bolt is screwed onto the upper side of the first clamp;

[0017] The support bracket also includes a second clamp fixed to the lower end of the support block. A second bolt is screwed to the lower side of the second clamp. Both the first clamp and the second clamp are U-shaped structural blocks that hold the flange of the H-beam steel in place and are fixed to the flange of the H-beam steel by tightening the first bolt and the second bolt respectively.

[0018] Furthermore, the wedge-shaped support includes a push block, a vertical hole is provided on the lower side of the push block, the upper end of the support block is located in the vertical hole, and an inclined groove is connected to the side wall of the vertical hole.

[0019] The push block is fixed with a tapered slider on its upper side, and a tapered groove is provided at the upper end of the vertical groove. The tapered slider and the tapered groove slide together. The tapered slider and the tapered groove ensure that the push block and the moving bracket are slidably connected, and can also drive the two to make vertical displacement. That is, when the wedge bracket is pushed to move laterally by the pushing mechanism, the moving bracket is moved simultaneously, which is convenient for use.

[0020] Furthermore, the pushing mechanism includes a stop rod, a disc spring, a mounting block, and an outer lifting member; the mounting block is slidably disposed in a vertical groove, and a rectangular through hole is provided on the outer side of the mounting block and opened on the movable bracket. The vertical length of the rectangular through hole is the stroke of the mounting block displacement, and the stop rod slides through the mounting block.

[0021] Specifically, a circular through hole is provided on the mounting block, and the diameter of the circular through hole is larger than the diameter of the abutment rod, leaving space for the abutment rod to tilt;

[0022] The disc spring is located between the mounting block and the wedge bracket. The force of the disc spring will push the wedge bracket inward. Through the cooperation of the inclined groove and the inclined block, the total length of the moving bracket and the support bracket is extended. At the same time, it can further prevent the total length of the moving bracket and the support bracket from shortening on its own, so as to increase the support performance of this support structure.

[0023] The outer end of the abutment is connected to the outer lifting member, which is used to pull the abutment and the wedge bracket outward, while simultaneously moving the wedge bracket outward, shortening the total length of the moving bracket and the supporting bracket, so as to dismantle this support structure.

[0024] Furthermore, the external lifting component includes a rotating seat, a pressure rod, and a connecting seat; the rotating seat is fixed to the outside of the movable bracket, the pressure rod is rotatably mounted on the rotating seat, the head of the pressure rod has an elongated hole, and the connecting seat is slidably mounted in the elongated hole so that the connecting seat can be displaced and rotated within a certain angle. The connecting seat and the support rod are connected by a threaded pair. The distance from the rotating seat to the head of the pressure rod is less than the distance from the rotating seat to the tail of the pressure rod, which saves effort when using based on the lever principle.

[0025] Furthermore, the inner end of the abutment is spherically hinged to the wedge-shaped bracket. Specifically, a spherical block is fixed to the inner end of the abutment, and a spherical groove is provided on the outer surface of the wedge-shaped bracket. The spherical block is rotatably installed in the spherical groove, which allows the abutment to be vertically flipped.

[0026] A method for using an H-beam anti-deformation device: When using the device, pressing the tail end of the pressure rod causes the head of the pressure rod to lift up, which pulls the abutment rod outward, further displacing the wedge-shaped bracket outward. Based on the cooperation of the inclined groove and the inclined block, the height of the wedge-shaped bracket can be reduced, and the moving bracket will also move downward, shortening the total length of the moving bracket and the support bracket, thus allowing the support structure to be disassembled.

[0027] During use, the disc spring is compressed and stores force. Pressing the pressure rod causes the first and second clamps to align and engage with the upper and lower flanges of the H-beam, respectively. Then, releasing the pressure rod causes the wedge bracket to move inward due to the force of the disc spring, extending the total length of the moving bracket and the supporting bracket to support the upper and lower flanges of the H-beam. The self-locking property of the inclined plane ensures that the inclined block will not move outward on its own when subjected to a force perpendicular to the flange of the H-beam. If necessary, the tail of the pressure rod can be bent outward, and the wedge bracket can be moved inward through the abutment rod to increase the support force on the upper and lower flanges of the H-beam.

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0030] The purpose of this invention is to provide an anti-deformation device for H-beams, which solves the problem of weak strength and easy deformation at the flanges of H-beam connection nodes. By using a movable bracket, a support bracket, and a wedge-shaped bracket, the flanges at the H-beam nodes can be reinforced and supported, effectively preventing deformation at the flanges and increasing the load-bearing capacity of the H-beams. The total length of the movable bracket and the support bracket can be easily adjusted by the pushing mechanism, so as to connect the movable bracket and the support bracket to the flanges at the H-beam nodes respectively, making operation convenient.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0041] Example 1

[0042] from Figure 1-6 As can be seen, the H-beam anti-deformation device of this embodiment includes an H-beam 1, a movable bracket 2, a support bracket 4, and a wedge bracket 3. The movable bracket 2 and the support bracket 4 are slidably connected. When the two slide, their total length can be adjusted. The wedge bracket 3 is abutted between the movable bracket 2 and the support bracket 4.

[0043] The wedge-shaped bracket 3 is located in the middle of the movable bracket 2 and the support bracket 4. At the same time, the upper and lower ends of the wedge-shaped bracket 3 abut against the movable bracket 2 and the support bracket 4 respectively, and the wedge-shaped bracket 3 can move laterally.

[0044] The bottom of the wedge-shaped bracket 3 is provided with a sloping groove 33, and correspondingly, the surface of the support bracket 4 is provided with a sloping block 43.

[0045] Multiple inclined blocks 43 are spaced apart on both sides of the support block 41. The number of inclined blocks 43 is equal to the number of inclined grooves 33 to increase the support capacity.

[0046] The angle of the inclined block 43 is 5°. When designing the tilt angle of the inclined block 43, the friction angle is ensured to be greater than or equal to the transmission angle. The self-locking property of the inclined surface is used to ensure that the inclined block 43 will not move outward on its own when subjected to a force perpendicular to the flange of the H-beam 1.

[0047] A pushing mechanism 5 is provided on the outside of the movable support 2. The side of the inclined groove 33 and the inclined block 43 closest to the pushing mechanism 5 is the lower end. The pushing mechanism 5 is used to push the wedge-shaped support 3 to move laterally. Under the squeezing cooperation of the inclined groove 33 and the inclined block 43, when the wedge-shaped support 3 is pushed inward, the total length of the movable support 2 and the support support 4 is extended to support the H-beam 1. When the wedge-shaped support 3 is pushed outward, the total length of the movable support 2 and the support support 4 is shortened, so that the support structure can be disassembled from the H-beam 1.

[0048] The movable support 2 includes a track 21, and a vertical groove 22 is provided in the track 21;

[0049] The support bracket 4 includes a support block 41 and a slide rail 42 fixed to one side of the support block 41. The support block 41 is slidably engaged with the vertical slide groove 22 inside the track 21 through the slide rail 42. The support block 41 is slidably inserted into the track 21. The vertical slide groove 22 is adapted to the cross section of the slide rail 42 to increase the stability of the support bracket 4 and the movable bracket 2.

[0050] To increase the stability of the connection between the movable support 2, the support bracket 4 and the flange of the H-beam 1, the movable support 2 also includes a first clamp 23 fixed to the upper side of the track 21, and a first bolt 24 is screwed onto the upper side of the first clamp 23.

[0051] The support bracket 4 also includes a second clamp 44 fixed to the lower end of the support block 41. A second bolt 45 is screwed to the lower side of the second clamp 44. Both the first clamp 23 and the second clamp 44 are U-shaped structural blocks that hold the flange of the H-beam 1 in place and are fixed to the flange of the H-beam 1 by locking the first bolt 24 and the second bolt 45 respectively.

[0052] The wedge-shaped bracket 3 includes a push block 31, a vertical hole 35 is provided on the lower side of the push block 31, the upper end of the support block 41 is located in the vertical hole 35, and the inclined groove 33 is connected to the side wall of the vertical hole 35.

[0053] A tapered slider 32 is fixed on the upper side of the push block 31. A tapered groove is provided at the upper end of the vertical slide groove 22. The tapered slider 32 slides in conjunction with the tapered groove. The tapered slider 32 and the tapered groove ensure that the push block 31 and the movable bracket 2 are slidably connected, and can also drive the two to make vertical displacement. That is, when the wedge bracket 3 is pushed to move laterally by the pushing mechanism 5, the movable bracket 2 is moved simultaneously, which is convenient for use.

[0054] Example 2

[0055] from Figure 1-8As can be seen, the H-beam anti-deformation device of this embodiment also includes a pushing mechanism 5. The pushing mechanism 5 includes a push rod 54, a disc spring 56, a mounting block 55 and an outer lifting member. The mounting block 55 is slidably disposed in the vertical slide groove 22. A rectangular through hole 25 is provided on the outer side of the mounting block 55 and is opened on the movable bracket 2. The vertical length of the rectangular through hole 25 is the stroke of the mounting block 55 displacement. The push rod 54 slides through the mounting block 55.

[0056] Specifically, a circular through hole is provided on the mounting block 55, and the diameter of the circular through hole is larger than the diameter of the abutment rod 54, leaving space for the abutment rod 54 to tilt.

[0057] The disc spring 56 is located between the mounting block 55 and the wedge bracket 3. The force of the disc spring 56 will push the wedge bracket 3 inward. Through the cooperation of the inclined groove 33 and the inclined block 43, the total length of the movable bracket 2 and the support bracket 4 is extended. At the same time, it can further prevent the total length of the movable bracket 2 and the support bracket 4 from shortening on its own, so as to increase the support performance of this support structure.

[0058] The outer end of the abutment 54 is connected to the outer lifting member, which is used to pull the abutment 54 and the wedge bracket 3 outward, and at the same time drive the wedge bracket 3 to move outward, shortening the total length of the moving bracket 2 and the supporting bracket 4, so as to remove this support structure.

[0059] The outer lifting component includes a rotating seat 52, a pressure rod 51, and a connecting seat 53. The rotating seat 52 is fixed to the outside of the movable bracket 2. The pressure rod 51 is rotatably mounted on the rotating seat 52. The head of the pressure rod 51 has an elongated hole 58. The connecting seat 53 is slidably mounted in the elongated hole 58 so that the connecting seat 53 can be displaced and rotated within a certain angle. The connecting seat 53 and the push rod 54 are connected by a threaded pair. The distance from the head of the rotating seat 52 to the head of the pressure rod 51 is less than the distance from the tail of the rotating seat 52 to the tail of the pressure rod 51. Based on the lever principle, this saves effort when using the device.

[0060] The inner end of the abutment 54 is spherically hinged to the wedge bracket 3. Specifically, a spherical block 57 is fixed to the inner end of the abutment 54, and a spherical groove 34 is opened on the outer surface of the wedge bracket 3. The spherical block 57 is rotatably installed in the spherical groove 34, which allows the abutment 54 to be vertically flipped.

[0061] A method for an H-beam anti-deformation device: When in use, pressing the tail end of the pressure rod 51 causes the head of the pressure rod 51 to lift up, which pulls the abutment rod 54 outward, further displacing the wedge-shaped bracket 3 outward. Based on the cooperation of the inclined groove 33 and the inclined block 43, the height of the wedge-shaped bracket 3 can be reduced, and the movable bracket 2 will also move downward, shortening the total length of the movable bracket 2 and the support bracket 4, thus allowing the support structure to be disassembled.

[0062] During use, the disc spring 56 is compressed and stores force; pressing the pressure rod 51 causes the first clamp 23 and the second clamp 44 to correspond to and engage with the upper and lower flanges of the H-beam 1, respectively. Then, the pressure rod 51 is released, and the wedge bracket 3 moves inward due to the force of the disc spring 56, extending the total length of the moving bracket 2 and the supporting bracket 4 to support the upper and lower flanges of the H-beam 1. The self-locking property of the inclined plane ensures that when the inclined block 43 is subjected to a force perpendicular to the flange of the H-beam 1, it will not move outward on its own. If necessary, the tail of the pressure rod 51 can be bent outward, and the wedge bracket 3 can be moved inward through the abutment rod 54 to increase the support force on the upper and lower flanges of the H-beam 1.

[0063] The purpose of this invention is to provide an anti-deformation device for H-beams, which solves the problem of weak strength and easy deformation at the flanges of H-beam connection nodes. By using a movable bracket, a support bracket, and a wedge-shaped bracket, the flanges at the H-beam nodes can be reinforced and supported, effectively preventing deformation at the flanges and increasing the load-bearing capacity of the H-beams. The total length of the movable bracket and the support bracket can be easily adjusted by the pushing mechanism, so as to connect the movable bracket and the support bracket to the flanges at the H-beam nodes respectively, making operation convenient.

[0064] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

When it is necessary to increase the support force on the upper and lower flanges of the H-beam (1), the tail of the pressure rod (51) is bent outward, and the wedge bracket (3) is moved inward through the abutment rod (54).
